At the bare minmum for Cisco VoIP you need to open up port 2000 for the skinny protocol and the RTP protocol ( Cant remember the protocol number off the top of my head )
It may require MGCP, H323 and possibly RTSP depending on the way you implemented it. And dont forget that QOS is a big issue with VoIP so you will have to enable support for IP Precedence/DSCP if FW1 has the capability.

What ports need to be opened and what is the way around if there are potential security threats? cheers _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
